Mistakes in the BAFTA winners and nominees for the 2009 awards (Oscars, Razzies)
This isn't a hugely detailed list - specific actors, etc. aren't mentioned (that's what the official award sites are for!). As such some films may be listed as both "winner" and "nominated" if, for example, two people from the same movie were up for the same award. Some may be missing if they have no entries on the site.
